A long time ago, Justin Sun published the TRON whitepaper which was an exact copy of ETH's whitepaper. Vitalik Buterin accused Justin Sun of "plagarism". It's likely TRON is a direct copy of Ethereum with a few minor tweaks. While there are stablecoins built on top of the TRON blockchain, there isn't a variety of dApps to choose from. Competitors are faring better in this regard. Who knows how long TRON will last? Just my thoughts
Undoubtedly, TRON as an investment has not achieved any significant success over the past 7 years, but in terms of adopting and utilization, TRON and its TRC20 network is much more useful and reliable than most altcoins, even among the older ones. TRON does not grow in value well, but almost all crypto services work with it. It is one of the few coins on the crypto market whose appeal is not in speculation, but in utility.
